Description

1,4-Bis(Trimethylsilyl)Benzene is a high-purity organosilicon compound featuring a benzene core symmetrically substituted with trimethylsilyl groups. This molecular architecture makes it a valuable silylating agent and versatile synthetic intermediate in advanced organic and organometallic chemistry. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and materials science sectors who require reliable, high-quality building blocks for complex synthesis.

Application

• Key Intermediate in Pharmaceutical Synthesis: Used in the preparation of active pharmaceutical ingredients (APIs) and complex organic molecules, particularly where silicon-based protecting groups are required.
• Precursor for Advanced Materials: Serves as a building block for silicon-containing polymers, liquid crystals, and organic light-emitting diodes (OLEDs).
• Silylating Agent: Employed to introduce the trimethylsilyl (TMS) group into organic molecules, altering their volatility, stability, or reactivity for analytical or synthetic purposes.
• Research & Development: A crucial reagent in academic and industrial R&D labs for exploring new synthetic pathways and novel silicon chemistry.
• Agrochemical Manufacturing: Used in the synthesis of silicon-based or silicon-modified crop protection agents and herbicides.
• Cross-Coupling Reactions: Acts as a reactant in palladium-catalyzed cross-coupling reactions, such as the Hiyama coupling, to form carbon-carbon bonds.

Quality Control

Our 1,4-Bis(Trimethylsilyl)Benzene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) documenting identity, assay, and impurity profiles are available for every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) for prolonged storage or after opening to prevent degradation. Keep away from strong bases and fluorides.
